CircuitWorks Heat Sink Grease

CircuitWorks® Heat Sink Grease silicone compound facilitates heat transfer away from electrical/electronic components. This heavy consistency material is thickened with a heat conductive filler to maintain a positive heat sink seal in electrical/electronic equipment.

Heat Sink Grease (CT40-5)

  • Silicone-base
  • Thermally stable from -52º F (-46º C) to 603º F (317º C)
  • Meets MIL-DTL-47113D Type I

Silicone Free Heat Sink Grease (CW7270)

  • Silicone free compound avoids silicone migration
  • Thermally stable from 5ºF/-15ºC to 392ºF/200ºC
  • Exceeds MIL-C-47113 for thermal conductivity

Boron Nitride Heat Sink Grease (CW7250, CW7250KG)

    • Provides maximum thermal conductivity with superior dielectric properties
    • Silicone free compound will not harden or dry out
    • Thermally stable from -99ºF/-73ºC to 392ºF/200ºC
    • Exceeds MIL-C-47113 for Thermal Conductivity

  • Facilitates heat transfer between circuit components and heat sinks
  • Excellent thermal and dielectric properties
  • Will not dry out, harden, or melt
  • Noncorrosive and nonflammable
